V OCONNOR, a citizen'of the United'f'States,

and a resident of thecity of New York,

borough of Brooklyn, in the county of 'Kings'- and State of vNew York,have invented -anew andlm roved-'TypeeWriter Ribbon- Spool, 'o' w ich'the'following" is a full,

' provided with a cast hu 'to which .theanges clear, and exactdescription.

The object of the; invention 'isV lio-provide a new and improved tyewriter 4ribb'on'spool are riveted, thus pennittingquick, convenient andaccurate assemblm vof the parte without the aid of. highly stherebyreduoing the cost of manufacturing hg).

led labor, and

to a minimum.

The invention consists of novel featuresand parts and combinations ofthe same, as will be more fully described hereinafter and. then pointedout inthe claim.

A practical embodiment of the invention is represented intheaceompanying drawings forming" a part of'this specification, in whichsimilar characters of reference indicate corresponding parts in alltheviews.

The terminals of the ends Aare riveted against the outer faces of 'the fliinges'B, B, so that therivet heads securely hold 'the flanges B, B, in position on the ends Aof theliub A and 'against the shoulders A.

on which-the spool' mounted to turn, the said shaft forming a usualolart bf the typet e spool is used.

thefiiunges arefprovided with lopenings 'B2 A,registering `with -a'groove A? lextending vlengthwise in the peripheral-face of the hub vA,to permit the insertion of. a pin .to hold 'thespool from turning. 'Thispin'iornis a usual part of theltfypewritig machine and hence-1t is notldeemed necessary to further describe or illustrate the same.

The retainer C is in the forni of a plate' 65 rovided along one edge'with teeth C (see 4') for engagement with the end of the lateterminatin in lugs CZ extending oosely into radial y-elongatedlslotsor-Ouidei Lways B", formed injthe flanges B. lT ie retainer C overlies aflat portion A5 formed on the peripheral face' 'o the hub A, and thelugs' C2v slightly project be ond vthe outer faces of the flanges B('see Figs. 2 and 4), to 75 allow the operator to take Vhold of theprojecting 'endsofgthe lugs' C?, with a view to raising the retainer C'suilioiently above the flattened portion A5to vPermit the operator theretainer C and the said flattened p'ortioi'v lace on the spool.
